Description
A Valley Switching Converter generally shows lower EMI
and
conventional hard-switched converter with a fixed
switching frequency. The FSQ-series is an integrated
Pulse-Width
SenseFET specifically designed for valley switching
operation with minimal external components. The PWM
controller
oscillator,
Blanking (LEB), optimized gate driver, internal soft-start,
temperature-compensated precise current sources for
loop compensation, and self-protection circuitry.
Compared with discrete MOSFET and PWM controller
solutions, the FSQ-series reduces total cost, component
count, size and weight; while simultaneously increasing
efficiency, productivity, and system reliability. This device
provides a basic platform that is well suited for cost-
effective designs of valley switching fly-back converters.
